VB.NET/C#-麦克风输入频率(db，hz) [英] VB.NET / C# - Microphone input frequency(db, hz)

问题描述

我正在寻找一种方法(代码示例)，使其几乎可以实时获取麦克风输入频率(赫兹)(可能是计时器?)并将其显示在label.text中.可以在VB.NET或C#中.
现在我已经通过wavein获得了声音阵列，但是我不知道如何通过fft计算频率?
像这样的声音阵列{120,121,132,114,186,220,112,113,121 ..}，
我获得频率后，如何确定声源是男人还是女人?
功能示例:
有人用麦克风说话，然后确定标签显示男人"或女人"在说的声音频率.
在此先感谢！

Hi,
I am looking for a way(code example) to be able to get the microphone input frequency(hertz) almost in real time(timer maybe?) and show it in a label.text. Can be in VB.NET or C#.
Now I have get the sound array by wavein ,but i don''t know how to calculate the frequency by fft?
The sound array like this {120,121,132,114,186,220,112,113,121..},
After i get the frequency how to determine the sound source is a man or woman?
Functional exemple:
Somebody say something in the microphone,and determine the sound frequency the lable show "man" or "women" is saying.
Thanks in advance!
